Abstract
AbstractA comprehensive investigation of propagation of new longitudinal electro‐kinetic modes and novel properties introduced due to presence of negatively charged particulates in semiconductor plasma is presented. By employing the multi‐fluid balance equations, a compact dispersion relation for the cases in which wave phase velocity is either larger or smaller than electron thermal velocity is derived. This dispersion relation is used to study wave phenomena and electro‐kinetic mode instability numerically. We find important modifications in electro‐kinetic branch as well as the existence of new modes of propagation in semiconductor plasma in presence of charged particulates. The results of this investigation should be useful in understanding the characteristics of longitudinal electro‐kinetic wave in semiconductor plasmas in presence of charged particulates whose main constituents are electrons, holes and negatively charged particulates.
